the "Smooth Green Snake," because the scales are not keeled. In 

 both, the anal plate is divided or bifid. The Green Snake has about 

 one hundred and fifty-five ventral plates, while the Grass Snake has 

 only about one hundred and forty. With the former the tail is 

 more than one-third the length of the entire body, and with the 

 latter the tail is less than one-third its entire length. The Green 

 Snake is described as having a conical head; neck very small; color 

 bright clear green, yellowish below; scales in seventeen rows; 

 ventral plates one hundred and fifty to one hundred and sixty- 

 five; tail more than one-third of the body, and the length reaching 

 thirtv inches.

This snake is found from southern New Jersey to Indiana and 

 southward, and is abundant in the southern part of the country. 

 It is a beautiful little snake, living on bushes and trees, as well 

 as among grass, and is shown by our Plate No. XXVI to be quite at 

 home in a tree. It feeds more upon insects than upon other crea 

 tures, and as it is entirely harmless should be protected rather than 

 destroyed. We regret that we have been able to study only two 

 specimens of this species from this State. One is from Lancaster 

 county and the other from Dauphin county, Ta. There are a few 

 from Pennsylvania in other collections. We respectfully request 

 readers to send us specimens of the green colored snakes which 

 thev mav meet in their rambles. They are absolutely harmless.
